l'o-'all @chum it may concern: Vlmown that we, GEORGE M.PEELPs,ofiBrooklym'in the county of Kings and 'S tate f NewYork, and ROBERTSTEWART, of Borf -dentown'n the county of Burlington and State ofNewJersey, have invented and madel anew motor-'audits connectionsandpartof the sig-fl l'nalfbomfdlig. 3 is a plan of the 'electricalfniot'or, and Fig. 4 isan elevation illustrative ofthe switch-lever; andcircuit-breaker.

.. Similar marks of reference denote the same parts Electrical signalshave before been applied to railroad-switches, so that when the'switchhas been changed to a turn-entail electrical circuit has been closed'and a bell rung, or other signal given. In this case the switch may beoff Xtli mainline, and it the battery is out of order or any oftheconnections interrupted no signal will be given. In our'apparatusthesignal is given when the-*circuit is broken; thereby a signal will begivenif the battery or any of the parts get out of order, as well as bylchanging the switch, thu'sf'renderin g thefapparatus perfectly safe insignaling danger orfits own wantof at- Wefemploy anjelectrical *motorthat fur-1 nishes--the '-powernecessary for moving the signahand whenthe circuit is broken and the 'motor has no further power to hold up thesignal said signal falls by its own weight.

vf In the drawing, we have showna box, a, in

.which is afla'g, b, that should -be' red. The

same is suspended by a cord, 2, over pulleys passing'to the electricmotor, and the box is also shown' with a space for receivingra lamp latnigh t, and' doors c d, the door c 'having a glass.

'danger. vV- Vhen it is lifted into the upper lpart of the boxthe'indication is safety.

-W'e do not, however, limit our apparatus -to any-particularconstruction oi signal, as tllat may be varied-as desired..

O ur electrical motor consists in a central shaft, e, around which isplaced a series of `armatures,=s tanding parallel tothe axis, and

in a circular range', so as to revolve just clear l of a circular rangeof electro-magnets, that aresustained lby a frame'or plate.

One wire of a battery connects with the ring` g and range ofcircuit-closing springs h, that Aare insulated from thefother parts'ofthe machine; and beneath' the. innerends `of thef springs is a.revolving ring with `pins or teeth,

that turns with the axis c and armatures, and

the'pins or teeth lift the springs in succession,Y breaking thecircuit,or allow them :to rest 'down upon studs 4 to close the -circuitthroughthe magnets f successively, so that said magnets acting to attract thearmatures at'the plied with the switch-lever l, is represented with itsprotecting cover removed.

The wires of the circuit' pass to the sprin gs' n and o,'f t hat Iareinsulated from the case m byv the block 6, and said springs u o havepoints contiguousto the center block r.

The. lever s stands between the 'springs wo;

and below the. lblock r, and it has insulated pins projecting' from itssides to take the springs u o. When. this lever s stands verti cally, inconsequence of 'being so held by the 'switch-lever l, when in place onthe niairr line, the springs .n o rest at the sides of the block r; butwhen the lever, l is moved it either causes the' lever s to press oneot! the springsv n or' o out ofeontactfwith the block r and-Abrea'lrthe,circuitv or elseitallows the spring t 'to act on'saidleversandbreak the circuitbe 'tween 'n and r andoperate the signal. v

proper point Agivea rotarymovenient toV the axis e, 'andproduc amotortha't 'can 'be ema The arrangement of the wires and connectionsbetween the switch or otherdevice for operating` the circuit-breaker andthe motorv will be understood by lthose yersed in telegcumstances.

XVe have represented the wires 10 and llfrom the switch circuit-breakerm as passing, one to the binding-screw 12 to the batter f, and ltheother through the relay-magnet u to the battery-screw 13.l i

The binding-screws 14 aud-15 to the local battery are connected, one tothe ring g and springs h ofthe motor, and the other to the `lever of thelocal magnet u,and thence to the plate i of the motor.

What We claim, and desire to secure by Letters Patent, is

raphy, and will vary according to local cir 1. A motor loperated, byelectricity and t ted, substantially as specified, toy remove and retainthe danger-signal while the circuit is closed, and to allow said signalto beshown when the circuit is broken, substantially as set v forth. l

2. The circuit-breaker formed of the springs n o, lever s, block t", andspring t', in combination-with the switch-lever Z, substantially as andfor the purposes specified.

In witness whereof we have hereunto set our signatures this 15th day ofJune, A l).
